This is a tough question! You see, the madder Hulk gets, the STRONGER he gets, and that means he can get super strong. Such a thing is fortuitous for one with a determination to smash.

Goku, on the other hand, was strong enough to blow up the entire... Earth? In season one? And he only got stronger? How much stronger? ...In the time it would take to say his power level, the universe would give birth to and vanquish a thousand suns?
